Square Pixel formats accompanied by a square pixel clock of the appropriate
frequency.
The SAA7115 can capture the serially coded data in the vertical blanking interval
(VBI-data) of several broadcast standards. It also incorporates also a frame locked
audio clock generation. This ensures that there is always the same number of audio
samples associated with a frame or set of fields. This prevents the loss of
synchronisation between video and audio, during capture or playback. Furthermore
the second analog onboard PLL optionally can be used to enhance this audio clock to
a low jitter frame locked audio clock. All the functions of the SAA7115 can be
controlled via I²C-bus.
Features
Video acquisition
Comb filter video decoder
Six analog inputs, internal analog source selectors (e.g.: 6 x CVBS or (2 x YC
and 2 CVBS) or (1 x YC and 4xCVBS))
Two built in analog anti-alias filters
